Title: Method for normalization of atmospheric conditions in face
Inventor: ALEKSIEIENKO SERHII OLEKSANDRO
IPC: E21F3/00
Filed: 2004-07-07
Abstract: Method for normalization of atmospheric conditions in face includes steps of preliminary treatment of coal massif and air supply to critical area of formation of face by system of through wells drilled in massif between transport and ventilation drifts inclined to line of breakage face. Each well in sequence undergoes multi-factor treatment. First one pumps out from each well stratal gases, after that one wets through it, and cools, coal massif. With approach of breakage face to well, level of its cooling is increased. At intersection of next well and surface of face, one supplies air to face through it. As the result, complex normalization of atmospheric conditions in face is provided by gas, dust and heat factors.

Abstract: In the manufacture of frames, particularly wooden frames, the glued faces have to be pressed together along the bevelled cuts. For this purpose a clamping frame is suggested which comprises a closed rectangular clamping frame consisting of a first frame portion (10) consisting of two limbs (10a, 10b) at right-angles to each other and a second frame portion (16) consisting of two limbs (16a, 16b) at right-angles to each other. The second frame portion (16) is displaceable relatively to the first frame portion (10) and the limbs (16a, 16b) of the second frame portion (16) project outwardly beyond the limbs (10a, 10b) of the first frame portion (10). On the outside of the limbs (10a, 10b) of the first frame portion and parallel thereto there are pull rods (18) which intersect at the corner of the first frame portion (10) and engage the projecting limb sections of the second frame portion (16). Clamps (22) can be applied to the sections of the limbs of the second frame portion (16) that project beyond the limbs of the first frame portion (10) as well as to the pull rods (18), which clamps are supported on the outside of the limbs of the first frame portion (10) and with which the second frame portion (16) can be tightened to the first frame portion (10).

The compressor suction line is connected to one chamber of a heat exchanger and a pressure reduction valve is connected in the suction line upstream of the heat exchanger. The pressure line extending from the compressor passes to an oil separator and then to the other chamber of the heat exchanger. The fall in pressure in the reduction valve and heating of the refrigerant in the heat exchanger causes the refrigerant to be in a gaseous state when reaching the compressor, which is a prerequisite for safe operation of the compressor. The pressure increase achieved in the compressor pump and cooling of the refrigerant in the heat exchanger enables the refrigerant to be delivered to a container, preferably in a liquid state.

Abstract: A method and device for separating most of the waste material from sewage effluent, which incinerates a large portion of the waste to dispose of the waste in an environmentally safe manner. After separation, the aqueous by-product from the sewage effluent is substantially waste free, allowing easy disposition or further treatment. The apparatus includes a housing and a filter in the housing to which the sewage effluent is introduced. The solid waste materials are trapped in the filter with a substantially aqueous by-product discharged from the device. A switch senses entry of the sewage effluent, starting operation of a heating element and a microwave generator which operate to substantially incinerate the waste material into an ash particulate. The gaseous by-products of the incineration are vented to the atmosphere and the ash particulate is vacummed into a temporary storage container.
